To all whom it may concern:

Be it known that I, Eimsros E. WINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Sorting Shoe-Stock; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines in which heel-lifts, or other pieces of shoe stock, are operated upon, and it is applicable particularly to machines for sorting or gradlng such pieces in accordance with their mass, although some of its features are not necessarily restricted to embodiment in a grading machine.

he present invention is an improvement on the machine for sorting or grading pieces of shoe stock illustrated and described in Letters Patent of the United States, No. 1,234,433, granted to me July 24, 1917. One object of the invention is to provide a machine of the kind in question with efficient and reliable means for transferring pieces, fromthe stack in which they are fed, to the carrier by which they are transferred to the various instrumentalities of the ma chine. To this end I employ means which are adapted to hold the pieces positively and to turn them from the vertical position, which they occupy in the stack, to the 'hori zontal position which they occupy in the carrier; and I further employ a series of such devices arranged circularly so that they may operate with an intermittent rotary movement.

A further object of the invention is to provide a machine of the kind in question with stop-mechanism operative automaticalljp to arrest the operation of the machine in case a iece of material is not properly placed wit relation to the operating instrumentalities ofthe" machine, and to this end I employ, in connection with the drive mechanism of the machine, a device for throwing tlIIS-dI'IVByIIlGChflHlSH1 out of operation, this device being controlled by engagementwith a iece of stock in case the piece is not propory positioned. l i

Another ob ect of the invention 13 to 1mthe conveyors on the feed-table;

a vertical .31 :fion on the line 8 8 in Fig. 6;,

prove the devices by which the pieces of stock, after they have been sorted or otherwise acted upon, are delivered in the form of stacks ready to be removed from the machine; and to this end the invention. comprises hoppers, for holding such stacks, which are adjustable in a novel and simple manner to til them to pieces of various sizes. and it further comprises positively acting means for introducing the pieces to and retaining them in such hoppers.

Another object of the invention is to improve the means by which the pieces of stock are carried to the operative inst-rumcntalities of the machine, particularly in such a manner as to render these means operative upon pieces of various sizes without the necessity of any adjustment; and to this end the in vention comprises means operativeto hold the pieces frictionally but firmly upon the carrier after they have been delivered thereto by the ;ce(l.-mec'hanism, and in the position in which they are so delivered, while the pieces are being carriedirom the point of feeding to the point at which they are discharged from the carrier.

Other objects of the invention, and the features of construction by which they are carried out, will be noted hereafter in connection with the description of the illustrat ed embodiment of the invention.

The preferred form of the invention, as applied to sorting heel-lifts, is illustrated in the accompanying drawings, in which Fig'u re 1 is a plan-view of a machine embodying the present invention certain parts being broken away m different horizontal planes to show the construction more fully; Figs. 2 and 3 are side-elevations of the same Inachine. seen from opposite directions; F ig. 4 is a side elevatiomon a larger scale than the preceding figures, of the feed-table and the parts associated therewith; Fig. 5 is a. r ear end-view of the same; Fig. 6 is a plan-view of the rear ortion of the ffeed-table, together with t e lift-pickers and the means for actuating [held 1 Fig. 7 is a p1anview of a portion of the mechanism for actuating F'g. 8 is Fig. 9 is a right-hand side-elevation of aportion of the teal-mechanism including, particularly, the means for actuating the r
